This dataset contains information about various aspects of the alarm communication network of African savannah herbivores. Data were collected in April 2015 and between September 2015 and October 2016 in the Masai Mara National Reserve, in southern Kenya (1°30’S, 35°10’E). Research focused on the 12 most common herbivore species in the ecosystem. For each of these species, the dataset provides information on vigilance rates, the probability to alarm call in response to different predators, the responsiveness to heterospecific alarm calls, as well as the relative abundance and grouping behaviour of species. Details on study species, study design and data analysis are provided in the supporting documentation.
